Enhanced Removal of Phenol from Aquatic Solution in a Schorl-catalyzed Fenton-like System by Acid-modified Schorl

Schorl modified by H2SO4 has been successfully developed to enhance schorl-catalyzed Fenton-like reaction for removal of phenol in an aqueous solution. The phenol removal percentage can be increased from 4% to 100% by the system of modified schorl and H2O2 Batch experiments indicate that the percent increases in removal of phenol by increasing the dosage of catalyst, temperature and initial concentration of H2O2 The results of XRD, FT-IR and SEM suggest that no new phases are formed after removal of phenol by modified schorl ICP-AES results reveal that more dissolution of iron results in higher catalytic oxidant activity in the system of modified schorl and H2O2 Besides minor adsorption, mineral-catalyzed Fenton-like reaction governs the process
